TEMA: How to order/setup a DID for Asterisk?

Notice that your server does not need to send calls to our servers but to receive calls from our servers; then you have to configure your Asterisk server to allow receiving calls from our Virtual Numbers DID's IPs (servers). Also, you don't need to authenticate in our servers but have to tell our servers where to point/map the DID; this operation can be done by yourself in our website as explained here: How to Forward DID Number to VOIP. As you can see on this guide, you will need to type at least your Server's IP (that you sent us) for mapping/forwarding.
As on here
How to Configure SIP-Asterisk with Phone2call's DIDs ? Anyway, the instructions are on this previous link.

hi, we are an enterprise of VoIP services, we want to buy a large quantity of DIDs to France and configure it on our pbx. I've configured my asterisk to send call to your server but I need to authenticate on your server and I've configured the trunk as on the link that you gave to me. this is my IP address XXXXXXXXXXX (real IP was sent privately).
thanks

That you got your SIP Asterisk to be working fine, it's a great news!!! . We are here to continue helping.

Great success!!
So I tested first with IAX: calls arrived fine, but audio was OK only 1-way, very bad the other. Possibly jitter or other codec settings needed to be adjusted. rather than wasting too much time there, I moved on...
Then I tested with SIP and worked like a charm!

For the record, here is my configuration on PIAF. For each of the IPs (as mentioned in your SIP-configuration guide) I created a trunk with a distinct name, and on each of those trunks I added the following to both the "PEER Details" and "USER Details" fields (change the "host" parameter to the corresponding trunk IP):

type=peer
nat=yes
insecure=very
host=46.19.209.10
dtmfmode=rfc2833
dtmf=rfc2833
context=from-trunk
allow=all

Of course the general NAT settings (found in Tools -> Advanced SIP Settings) need to be there, but in my case they were already configured. I had a dynamic DNS service already working, so using this same hostname completed the trick.

Will be ordering the DID shortly
Thanks for the help

Could not find the time to test yet. Hopefully during the weekend. I may test with IAX rather than SIP first, as the configuration seems simpler and see how it goes.
I'll be back

Did you manage to get the DID working?
